Ninian Southern Platform has a history of significant in-service weld defects and associated problems. As such Pre and Post Winter integrity inspections are required upon the major structural components on a Bi-annual basis in accordance with the integrity driven inspection plan. FMD was carried out on platform members, riser stubs and clamp guide frames as well as TOFD and ACFM upon high priority welds. There was a strong focus on this particular campaign by Canadian Natural Resources as the results would drive decisions as to whether or not to carry out a further hyperbaric weld repairs.

Smart Subsea Solutions were required to work closely with the Structural TA to define the scope of work, select an appropriate contractor, and review and approve offshore work pack as well as management of the subsea contractor throughout. The scope was completed within budget and 2 days ahead of schedule through effective management of SIMOPS offshore.
